Product Overview

The FireAngel HW1-R heat alarm is mains powered with a replaceable 9V back-up battery, central silence button, and a dedicated test button. Up to 12 W1-R and W1-PF series alarms can be interlinked together via a dedicated cable, including the CW1-PF-T mains powered carbon monoxide alarm, to provide full coverage and reliable warning of possible danger throughout the premises. To ensure that there is a back-up in case of a mains power failure, these alarms also feature a 'safety clip' which prevents them from being fitted to the base plate without a battery. Two LED status indicators are located on either side of the alarm's test button, one of which will light up to indicate a fault or alarm when necessary and the other showing whether or not mains power is active.

FAQs (2)
Q. I want to install an interlinked smoke alarm system throughout my home, but what type of smoke alarms do I need in different rooms?

We recommend a heat alarm in the kitchen, optical alarms in living rooms and hallway and ionisation alarms on landings.

Q. is there a different alarm sound for optical and heat sensors to tell you the difference in what kind of fire it is?

There is only one alarm sound type when a fire is detected, when interconnected all smoke and heat alarms will sound. However only the triggered alarm will have a rapidly flashing red indicator.
